Date:  Apr 22 2009
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 3.x prior to 3.0.9
Description:   A vulnerability was reported in Mozilla Firefox. A remote user can execute arbitrary JavaScript in the context of another domain.

The XPCNativeWrapper.toString function may be executed in the wrong context, allowing arbitrary code to be executed within the context of another domain (including chrome).

Mozilla SeaMonkey is affected.

Mozilla Thunderbird may be affected if JavaScript is enabled (not the default configuration).
